For those who are curious it's properly balanced. There are 24 slots available. Pairs: 1-13, 2-14, 6-18, 9-21, 10-22 Triple: 8-16-24 All pairs and triples have their centers of mass on the rotation axis.

What do you do if there's a prime number of test tubes, like the thirteen in the picture?

If you don't want to figure out some awkward balancing techniques, you can just use a balance tube. Fill a tube with water to a similar height of the tube it opposes.

For a 24-slot centrifuge, 5 pairs and 1 triple will balance 13 tubes, as is described in the comment you replied to.

Here's a video that also explains it: The Centrifuge Problem - Numberphile

They just explained it. If you have 3 you put them on 8-16-24. Everything else will be pairs which you put across from each other.
